You may have already heard JAX-RS 2.0 (JSR-339) has been released. This is a very good news for Java developers building their RESTful HTTP applications and here are the reasons why.

The 2.0 API  offers a lot of new enhancements on top of already very capable JAX-RS 1.1 (JSR-311) API and spec. It has really been a very serious push to the next level across all the API and the specification text. And what is really good is that the community can ...

The latest Cellar release (2.2.5) didn’t work with the new Karaf branch and release: 2.3.0. If the first purpose of Cellar 2.3.0 is to be able to work with Karaf 2.3.x, actually, it’s more than that. Let’s take a tour in the new Apache Karaf Cellar 2.3.0. Apache Karaf 2.3.x support Cellar 2.3.0 is fully

Apache CXF 2.7.5 has been released. The list of issues fixed is available here. The following security fixes of note have been made in this release:

• The OpenSAML dependency has been upgraded from 2.5.1 to 2.5.3.
• A change was made to the logic the STS uses to encrypt tokens that it issues. Previously it threw an exception if a key could not be found (at either service or at a more generic level) to use to encrypt the token. Now it only encrypts the ...

This extension will be available in CXF release 2.7.6 which is not yet available. But you can run tests with the SNAPSHOT build till this version is released. Please provide feedback to the CXF mailing list.

Different logging frameworks (SLF4J, Log4J, Logback, JUL) can be used to log events for Apache CXF STS. The configuration allows to define which logger should log messages till to which log level. That works fine to drill down generic issues but ...

With my new gig at Talend I have requested a MacBook Pro as a company computer, thinking that since I’m now an architect I will have to do more writing and (god forbid) slides. Of course I will continue to develop software, both for the company and in my open source work. For years, my preferred development platform has been Unix (shows how old I am, I really mean Unix) or Linux. And I have had to work on all three of Windows, Linux and the ...

After many years of leading Oakland Software to develop really good data transformation technology, I have moved to a new phase, having sold these assets to Talend. A little while ago, I joined Talend as a Senior Architect responsible for data transformation as well as other cross product issues and I’m very excited to be part of this team of extremely bright and talented folks.

For quite a while now the Oakland Data Transformer has worked ...

About a year ago, I have gotten involved pretty extensively in the Jenkins EC2 plugin where I’m now the maintainer. This was motivated by wanting to move my company’s (Oakland Software — now mostly part of Talend) build process to EC2 and finding out that it was simply not possible unless some significant work was done on the plugin. Seeing that the plugin was missing an active maintainer, I requested the responsibility (which was ...

When deploying a web service provider to a J2EE server such as Oracle WebLogic or IBM WebSphere Application Server it's probably easiest to first try to deploy as a WAR and see if that will work. However, due to classloader issues or a desire to take advantage of container-specific configuration you may find yourself needing to deploy your web service as an enterprise archive (EAR). This sample converts my WAR-based DoubleIt web service tutorial to ...

One of the new features in Apache CXF 2.7.x that I worked hard on was the introduction of support for WS-Discovery. WS-Discovery is basically a standard way for a service to announce when it’s available as well as standard way to probe the network for services that meet certain criteria and have the services that

I described in a previous blog how to configure the CXF STS for an LDAP directory for authentication and to retrieve user claims (attributes). The new release 2.7.5 of CXF provides extended support for roles managed in a LDAP directory. In previous versions, the LdapClaimsHandler added groups as roles if the groups were assigned to a multi-value attribute of the user. The new release provides an LdapGroupClaimsHandler which supports the case where an ...

At least for some time the whole world seemed to only talk about ESB and webservices. These technologies have their place in integration but they are quite complex and starting with them means you have to invest a lot of time and or money. Recently around the release of Java EE 6 the idea of simplicity came back to the Enterprise ...

Some exercise and diet lessons I've learned through the years:

Exercise:

1. Switch from per-day to per-week discipline. For many years I tried to exercise a set amount each day or every other day but would find my discipline would soon wane for one reason or another, causing difficulty restarting and getting back into a groove. About six years ago I switched to per-week discipline, which I've been able to adhere to 100% since then, amazing ...

Glassfish Jersey provides roughly three dozen RESTful samples (zip) (SVN) in its Version 1.17 (JAX-RS 1.1 compatible) release. I thought it would be useful to convert several of the examples to Apache CXF to see the changes needed for them to run. I have the converted samples stored on GitHub for all to view/download -- they can obtained via the download ZIP button or via the Git git clone -v git://github.com/gmazza/jersey-samples-on-cxf.git ...

He gave a broad overview of the history and applications of computer vision over the decades, successes and challenges, and current techniques and goals in the field. My notes from the meeting:

• Early research in computer vision started in the 1960's by the U.S. Post Office, with the goal of having ...

Saturday, I decided to upgrade to Ubuntu 13.04. I used Ubuntu 12.04 LTS for a long time (since the release date). So the first step was to upgrade to Ubuntu 12.10: no problem with this upgrade, it works straight forward. After that I upgraded to 13.04, and I had the following issues. Upgrade to AMD

One of the main benefits OpenStack provides is ...

Data Business DC is a sub-organization of Data Community DC, and this presentation was part of Big Data Week Washington. The slides from all three presentations are available online. My notes from the presentations:
